The diversion tunnel plug is a key project for the safety of water conservancy and hydropower projects. Wedge-shaped plugs are widely used in engineering. There are many calculation methods for columnar plug, but not so much for the wedge-shaped plug. Based on the design scheme of the diversion tunnel plug in Karot power station, this paper carried out the theoretical and numerical simulation analysis. Through the force analysis of the wedge, the calculation method of the hydraulic pressure bearing capacity of the wedge-shaped plug was proposed. The comparative analysis of wedge and columnar plug safety was carried out by three-dimensional elastoplastic numerical simulation. The result shows that the maximum deformation under the calibration water level of the wedge-shaped plug was 0.8 mm, and its overload safety factor was 1.08 times that of the columnar plug. By comparing the numerical simulation with the formula calculation results, the rationality and accuracy of the calculation method for the bearing capacity of the wedge-shaped plug were verified. The research results have important guiding value for the design of wedge-shaped block.

导流洞封堵体是水利水电工程蓄水后确保过流安全的关键性工程,目前针对柱形封堵体的计算方法成果较多,但对工程中应用较多的楔形封堵体,设计方法尚不多见。以Karot电站导流洞封堵体设计方案为例开展理论和数值模拟分析,通过楔形体受力分析,提出了楔形封堵体水压承载能力的计算方法,并采用三维弹塑性数值模拟方法,对比分析了扩挖楔形和柱状封堵体,结果表明扩挖楔形封堵体校核水位下最大变形0.8 mm,其超载安全系数是圆柱形封堵体的1.08倍。并通过数值模拟结果与公式计算结果的对比,验证了楔形封堵体承载力计算方法的合理性和准确性,对于楔形封堵体的设计具有重要的指导作用。

导流洞封堵体是水利水电工程蓄水后确保过流安全的关键性工程,目前针对柱形封堵体的计算方法成果较多,但对工程中应用较多的楔形封堵体,设计方法尚不多见。以Karot电站导流洞封堵体设计方案为例开展理论和数值模拟分析,通过楔形体受力分析,提出了楔形封堵体水压承载能力的计算方法,并采用三维弹塑性数值模拟方法,对比分析了扩挖楔形和柱状封堵体,结果表明扩挖楔形封堵体校核水位下最大变形0.8 mm,其超载安全系数是圆柱形封堵体的1.08倍。并通过数值模拟结果与公式计算结果的对比,验证了楔形封堵体承载力计算方法的合理性和准确性,对于楔形封堵体的设计具有重要的指导作用。

The diversion tunnel plug is a key project for the safety of water conservancy and hydropower projects. Wedge-shaped plugs are widely used in engineering. There are many calculation methods for columnar plug, but not so much for the wedge-shaped plug. Based on the design scheme of the diversion tunnel plug in Karot power station, this paper carried out the theoretical and numerical simulation analysis. Through the force analysis of the wedge, the calculation method of the hydraulic pressure bearing capacity of the wedge-shaped plug was proposed. The comparative analysis of wedge and columnar plug safety was carried out by three-dimensional elastoplastic numerical simulation. The result shows that the maximum deformation under the calibration water level of the wedge-shaped plug was 0.8 mm, and its overload safety factor was 1.08 times that of the columnar plug. By comparing the numerical simulation with the formula calculation results, the rationality and accuracy of the calculation method for the bearing capacity of the wedge-shaped plug were verified. The research results have important guiding value for the design of wedge-shaped block.
